Water-aided insertion of the colonoscope has been repeatedly proven to beneficial in terms of lower discomfort and need for sedation during colonoscopy. Patients with inflammatory bowel diseases (IBD) undergo repeated colonoscopy in course of their disease. According to our preliminary experience, water immersion could be beneficial while scoping these patients. As far as the investigators know, water-aided colonoscopy has never been studied in this indication. Results of our trial might support use of water-aided colonoscopy in common practice and decrease associated discomfort in IBD patients.

Further study details as provided by Vitkovice Hospital:

Primary Outcome Measures:
  • Success rate of unsedated colonoscopy [ Time Frame: at the end of each colonoscopy ] [ Designated as safety issue: No ]
    Successful unsedated colonoscopy is defined as reaching the cecum by using given insertion technique without administering sedation.

Secondary Outcome Measures:
  • Discomfort during colonoscopy [ Time Frame: at the end of each colonoscopy ] [ Designated as safety issue: No ]
    Discomfort level using visual continuous scale 0-10 (0 = no pain, 10 = worst pain).

  • Cecal intubation time [ Time Frame: while reaching the cecum ] [ Designated as safety issue: No ]
    Cecal intubation time is defined as time between colonoscope introduction into the anus and reaching the cecum.
